Day 9: ECS Services: Deploying and Managing Tasks

From Day 8, tasks are one-off. Services run tasks continuously.

Creating a Service

Console: ECS > Clusters > my-cluster > Create service > Fargate, task def: my-task, desired tasks: 1.

CLI:

aws ecs create-service --cluster my-cluster --service-name my-service --task-definition my-task --desired-count 1 --launch-type FARGATE --network-configuration "awsvpcConfiguration={subnets=[subnet-id],securityGroups=[sg-id],assignPublicIp=ENABLED}"

Access via public IP (from task details).

Managing Services

Update: aws ecs update-service --cluster my-cluster --service my-service --desired-count 2

Rollback: Via console revisions.

Delete: aws ecs delete-service --cluster my-cluster --service my-service --force

Today’s Takeaway

Services deployed!
